STAMP-CANCELING MACHINE.

T 0 all whom it may concern Be it known that I, Fniioiimc on Corrnr, engineer, a citizen of Switzerland, residing at Lausanne, Canton of Vaud, in the Confederation of Switzerland, have invented certain new and useful Improvements in Stamp-Canceling Machines, of which the following is a specification.

My invention relates to improvements in and relating to stamp canceling machines.

The machine made in accordance with my invention preferably comprises a die, an inking roller and devices adapted to per- .mit an oscillating movement of the die as well as the inking roller and the parts are arranged and operated so as to take the ink from the surface of an ink pad and to automatically ink the surface of the die at each reciprocating movement of the device.

My improved machine is intended to be employed in the post oflices and permits a rapid obliteration of letters and other matters.

The accompanying drawing illustrates by way of example an embodiment of my invention.

Figure '1 is an elevation. Fig. 2 is a front view. Fig. 3 is a side view of the die on a somewhat enlarged scale. Fig. A is a detailed view showing the inking device of the die.

Similar letters refer to similar parts throughout the several views.

The machine as illustrated is adapted to be driven by hand, It comprises a vertical support a with a base which is intended to be fixed on a table for receiving the objects to be canceled or obliterated. This support has two horizontal arms a and a at the end of which two part crank-shaft b is pivoted. Pivoted on the cross bar 12 of the same is a frame 0, which carries the stamping device proper. This device comprises a vertical shaft (Z which is adapted to slide vertically in the ends of two arms 0 and c of the frame 0. A spring 6 tends to force the shaft (Z upwardly and normally to maintain it in its highest position. An arm (Z is fixed on the shaft (Z and the free end thereof is arranged to slide in a groove in a bar 0 of the frame 0, to prevent the shaft d from rotating. The shaft (Z is provided at its lower end with a member 7" which carries a die 9 as shown in Figs. 1, 2 and 3, and a pin h on which a connecting rod 71. is pivoted, which transmits the Specification of Letters Patent.

movement imparted to the shaft (Z by means of a handle 71 to the elements which cause icalhe inking of the printing surface of the An inking roller j is mounted on the ends of the branches of a fork is (Fig. 4:),moi1nted on an arbor m which is parallel to the roller This arbor m is surrounded by a spring adapted to maintain the {roller 7' against the printing surface of the die 9. The arbor m is carried by two arms a and n which are parallel to each other and fastened on an arbor 0, which is parallel to the arbor m and is carried by a support 0 which is fixed in a bracket secured to the frame 0, and to this bracket is also connected the inking pad hereinafter described. The frame 0 is furthermore provided with an inking device consisting of a semi-circular support piece 1 carrying an ink-pad 1" on whlch the roller 7' may roll. The member f carries a device for holding in position the object to be stamped and this consists of a rod q adapted to slide in a sleeve and to be pressed downwardly by a spring The above described machine works in the following manner: The object 8 to be canceled or obliterated is placed in front of and beneath the die on a cushion or the like provided on the table which carries the machine. The portion 77 of the handle 2' is taken for example between the forefinger and the middle finger of the left hand of the operator and by depressing the portion 71 the shaft of is moved downwardly until the die 9 strikes the object 8. At the same time the connecting rod h, the arms a and a and therefore the arbor m and the fork is are also moved. In this movement, the roller j rolls on the surface of the die 9 and inks the same until the surface of the die reaches the plane of the lower end of the ink pad r of the ink ing device 1. At this moment the roller which is pulled by the arms a and n begins to roll on the ink pad 7" and inks itself. The roller is therefore positively drawn over the underside of the die during the descending movement of the same. Before the printing surface of the die reaches the object 8, the head of the rod 9 engages and presses on the object .9 and maintains it in place during the cancellation. After the object 8 has been canceled or obliterated the spring 0 raises the shaft d and all the elements connected to it into their normal positions. A spring t prevents the top part of the member from Owing to the contacting with the arm 0 double crank shaft 7) pivoted to the arms a and a of the support a it is possible to give to the die a horizontal swaying movement. It is therefore easy to cancel several post-age stamps afiixed to a common piece of mail matter, without shifting the position of this matter but simply by displacing the frame 0 with the hand holding the handle i.

The die 9 which often must be removed in order to change the hours for instance, is provided as usual with a tail 9 which enters the member f and is maintained in the same by means of a spring f which may be controlled by a button f For removing the die 9 the shaft cl is for instance pushed down until the roller touches the ink-pad 7 then the button f is pressed and the die 9 is unlocked and falls out. After the double pin a has been removed the disks of the die may be rotated so as to change the numbers indicating the date or hours.

The fork is may oscillate on a pin Z which is perpendicular to the axis of the roller, the oscillating movements being limited by the branches of a small fork 'v. For this reason the roller always makes perfect contact both with the surface of the die to be inked or with the ink pad T.

For removing the roller j, the screws j and j (Fig. 4:) which are provided with a cylindrical hollow part 7' through which passes the arbor of the roller, are unscrewed from slots in the ends of the fork 70 whereby the ends of the arbor of the roller are liberated and may be withdrawn from the slots. In an analogous manner the arbor 0 may be removed by unscrewing the screws 0 which also have a hollow cylindrical part, whereafter this arbor may be withdrawn from slots provided in the ends of the arms carrying it.

I claim as my invention: 7 g

1. A stamp canceling machine comprising a support, a two-part frame connected to the support to swing horizontally thereon, a shaft movable vertically in the said frame, a device detachably connected to the said shaft at the lower end thereof, a die connected to the said device, an inking pad secured to the said frame, a support carried by the said frame, a pair of spaced arms pivotally mounted on the said support, an arbor ex-,

tending between the said arms,'a pin fixed on the said arbor, a roller frame revolubly mounted on the said pin, an inking roller secured in the said roller frame, and means for connecting the said spaced arms to the said shaft so that the same and the inking roller are actuated by the movement of the shaft.

2. A stamp canceling machine comprising a support, a two-part frame connected to the support to swing horizontally thereon, a shaft movable vertically in the said frame, a device detachably connected to the said shaft at the lower end thereof, a die connected to the said device, an inking pad secured to the said frame, a support carried by the said frame, a pair of spaced arms pivotally mounted on the said support, an arbor extending between the said arms, a pin fixed on the saidarbor, a roller frame revolubly mounted on the said pin, an inking roller secured in the said roller frame, a pin fixed in the lower portion of the said shaft, and a link connecting the last aforesaid pin with the said spaced arms.

In testimony whereof I have aiiixed my signature in presence of two witnesses.
